  • ASMedia is the only controller IC manufacturer that can be trusted for these IME. They also have the best Linux support compared to the other options and support pass-through commands. These are commonly found in USB DAS enclosures, and a very small fraction of single disk SATA enclosures

    Innostor controllers max out at SATA 2 and lock up when you issue pass-through commands (e.g. to read SMART data). These also return an incorrect serial number. These are commonly found in ultra cheap desktop hard drive docks, and 40pin IDE/44pin IDE/SATA to USB converters

    JMicron controllers (not affiliated with the reputable Micron) should be avoided unless you know what you are doing… UASP is flaky, and there are hacky kernel boot time parameters required to get these working on Raspberry Pi boards. Unfortunately these are the most popular ones on the market due to very low cost










  • Not the case with ARM processors sadly, IMO they’re a bit of a mess from that perspective. Proprietary blobs for hardware, unusual kernel hacks for some devices, and no device tree support so you can’t just boot any image on any device. I think Windows for ARM encouraged some standardization in that regard, but for the most part looking at Android devices it’s still very much the wild west.

    This is one of the many reasons why Raspberry Pi ARM boards remain popular for the time being, despite there being so many other cheap alternatives available: they actually keep supporting their old boards & ensure hardware on their boards works from the get-go.

    There are also some rare cases where Raspberry Pi rewrite open source implementations of Broadcom’s proprietary blob drivers, in one instance for the built in CSI (optional camera)



  • I wholeheartedly agree with this tbh. Love FreeCAD for my 3D printing stuff, pretty much use it daily, however compared to something like Solidworks or AutoCAD it would be torture IMO to willingly chose FreeCAD for a complex real world product.

    The biggest roadblock for FreeCAD right now is that is isn’t that forgiving, you often have to go into a “technical” way of thinking to work around its quirks. The reality is, designers want to design, not become technical experts at navigating FreeCAD.

    Even something like creating a thread shouldn’t be as involved as FreeCAD makes it - once you get used to it it’s OK, but in other CAD solutions it’s often as simple as clicking a hole and choosing a thread creation tool…
